I've installed the correct driver with the release on February. Since then they had worked very well.
Yesterday, after certain time, and after 11.3.1 update of Big Sur, DDJ 1000 shows "No Audio Driver" but audio was sent to the correct channel and send through the master output. Also after the reinstallation of the correct driver and a complete restart, the problem was the same.
The workaround is open the “DDJ-1000 driver version display utility” and leave it open whilst using rekordbox.
Could you fix this little bug, please?
